Description:Oikos is a journal issued by the Nordic Ecological Society and is one of the leading peer-reviewed journals in ecology.

Oikos publishes original and innovative research on all aspects of ecology. Emphasis is on theoretical and empirical work aimed at generalization and synthesis across taxa, systems and ecological disciplines. Papers should be well founded in ecological theory and contribute to new developments in ecology by reporting novel theory or critical experimental results. Confirming or extending the established literature is given less priority. Synthesis of new and emerging fields in ecology and beyond is encouraged. Papers of review character should should strive for conceptual unification and being a point of departure for future work rather that restrospective summaries of established fields or topics.

The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

We report the results of an experiment using water-filled container analogues of natural treeholes placed in a subtropical rainforest. The source of energy in both experimental and natural systems is detrital leaves. This feature allows the productivity of the systems to be controlled and the effects on various aspects of food web structure to be measured. Ten-fold and hundred-fold reductions in energy input reduced food chain lengths by an extra link. The principal predator was less prevalent in less productive habitat units. Food webs with fewer trophic links and fewer species were found in habitat units that were less productive. Numbers of species, trophic links and abundance of the most common prey species increased during food web assembly. Interestingly, a natural perturbation created by low rainfall caused numbers of species, trophic links and food chain length to be temporarily reduced at 36 weeks. The effect on food chain length was most marked in the most productive system. This demonstrated the influence of dynamic constraints at a local spatial scale during food web assembly. While relatively long food chains were possible only in the most productive systems, these systems were especially vulnerable to external perturbations.
